Tanzanite was discovered relatively late and was not known until 1967. But it then quickly became famous in the international market. Gemologists called it the “Century Gem” of the 20th century. Its unique origin and color have fascinated many jewelry lovers.About 90% of Tanzanite in this world is sold by those jewelers who are the members of ICA (the International Colored Gemstone Association, the leader in colored gemstone industry, and its members are extremely ethical.) This fairly reliable sales channel avoids Tanzanite being handled by unprofessional businessmen.In recent years, the price of Tanzanite has risen steadily.
